This was an excellent tour. I was most impressed with the amount of teaching they did in order to make sure you were safe and informed. If you only Scuba once a year as I do I appreciated the reminders. The reef was better than any other reef I'd seen but I was disappointed that it was 'half dead' even there. That's why I gave it a 4 star. Lots of varieties of fish and good visibility. The staff on the boat were all very professional and made it a very pleasurable day. Good food too! My friend and I wandered a little far and were surprised that the current was so strong trying to get back to the boat. They did warn us and they left a long rope out the back to pull yourself back with but it had drifted away and we couldn't find it when he needed it. There wasn't anything they could have done about that. They told us how to signal them if we needed them but you know how men are :! I can't think of one thing they could have changed or improved on. It was excellent and a beautiful day.

Definitely worth doing.
Very expensive and lots of up- selling going on from scuba trips, scuba motorcycles, helicopter rodeos and more.
Wish we had more time to actually snorkel.
Beware... if you get seasick in any way - this is not the trip for you.

The trip was expertly guided by friendly and professional tour/snorkel/diving instructors. They explained everything clearly, ran the entire day's activities on time, and emphasized safety. The day was gloriously sunny, the water warm, the setting beautiful, and the Great Barrier Reef was simply unforgettable. Two teas and a tasty buffet lunch included in the cost. We LOVED every minute of the three snorkel dives on this wonderful trip!! Highly recommended and great value for the cost.

The tour was great. Plenty of space even though there were a lot of people on the boat. When it is time to get back on the boat though they want you on and standing in one spot asap so they can do their count...feels rushed at that point. Also, the times provided by Viator were incorrect. We showed up at the time our Viator confirmation told us to and turns out the boat had left! This would have been devastating as it was the only reason we went to Cairns. The boat had to return to drop off a sick passenger so we got lucky. Viator needs to coordinate closer with the company.

The team at Great Adventures was awesome. This was a time to never forget. The boat was perfect. The equipment spot on. Few things to remember before you go out: bring a towel, or a few of them. SPF of course. And hire a camera before you get on the boat! I didn't need one personally waterproof camera, so hiring one was perfect. They do that on the boat as well if you forget.
I do wish the food was a bit better, but I get that they can only do so much.
